Experience with Instant Live recording?

The Silk Road Project is going to be in town in a few days and I didn't want to pay the top dollar for seats, but noticed that they will be recorded live by "Instant Live" recordings. Has anyone purchased one of these CD's? Is the sound quality worth the $25.99 they are asking?
I have many Instant Live recordings, mostly by the Allman Brothers Band, they are excellent sounding recordings. I belived they rival any "label" released live recordings.
I have a Hydra (Particle w/Mickey Hart)and it is quite good. Although my experience has been that these are usually only available at the event, so not sure how it helps you.
